To (all who/It it vita/y concern.

Be it known that I, JOSEPH WV. SOMMER, a citizen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Coiling-Spindles and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention has reference to mechanism for coiling one wire around another, such as a stay-wire around a strand-wire, in wirefence making, but may be employed for other and various uses.

Theinvention has for its further object a coiling-spindle through which is adapted to be fed a continuous wire and in the provision of new and improved mechanism at the head of the spindle to insure the tight wrapping of a wire around said continuous wire.

A further object of this invention is a coiling-spindle provided with a longitudinal opening, a sleeve supported on the head end of the spindle to revolve intermittingly during such rotation of its spindle, the arrangement of the spindle and sleeve being such that the wire-opening in the spindle is eccentrically disposed with reference to the center of said sleeve.

The invention consists, further, of a spindle; a stem carried in the head end of the spindle and having a portion extending above the upper end of said spindle, the stem fixed for continuous rotation with its spindle; a sleeve eccentrically carried upon the upper end of the stem and so attached to said stem that it is intermittingly actuated during the continuous rotation of the spindle and its stem, and in the provision of a spring coiled around the spindle, one end thereof secured to the spindle and the opposite end secured to the sleeve provided for the purpose of increasing the speed of rotation of the sleeve at predetermined intervals.

Further objects and aims of the invention will become clear from the following specification and the drawings forming a part thereof, in which- Figure 1 is an elevation of a coiling-spindle embodying my improvements. Fig. 2 is a vertical section through the spindle. Fig. 3 is a vertical section and a plan view of the stem carried in the spindle. Figs. 4, 5, 6, and 7 are plan views of a spindle containing my improvements and showing four different steps in the operation of the coiler coiling one wire around another. Figs. 8 and 9 are vertical cross-sections taken oppositely to each other through the sleeve carried by the stem at the head of the spindle.

Like numerals of reference indicate corresponding parts throughout the figures.

1 denotes a tubular spindle which may be of any desired length, having the central longitudinal opening 2 extending through the spindle, and at 3 the opening through the spindle is made much greater in diameter and provides a shoulder 4. The spindle may be journaled in any suitable support and at any desired angle and may be driven, as shown in Fig. 1, by securing a gear-wheel 5 to the spindle and drive the same from a suitable source of power, or other well-known driving means may be substituted therefor.

In the head end of the spindle and within the enlarged opening 3 thereof is carried a stem 6, the same resting upon the shoulder 4, and the body of the stem extends up beyond the outer edge of the spindle 1. The body of the stem 6 above the upper end of the spindle is somewhat reduced in diameter, and the center of such reduced portion is eccentric to the center of its lower portion and the spindle 1, in which it is carried. The upper end of the stem is beveled, as at 7, and extending through the center of the lower portion of the stem 6 is a tubular opening 8, which also extends through the body of said stem and is eccentric to the center of the upper reduced portion of said stem, the lower portion of the opening 8 being tapered outwardly to the diameter of the opening 2 in the spindle 1 for ease in passing a wire up through the spindle and its stem. The stem 6 is fixedly carried in the spindle 1 for continuous rotation therewith and so held by means of a transverse pin 9, carried through the body of the spindle 1 and the lower body ortion of the stem 6, and the pin 9 is provided with the transverse opening 10, which coincides with and becomes a part of the opening 8 in the spindle 6.

On the upper extended portion of the stem 6, which is that portion above the upper end of the spindle 1, is carried a sleeve or similar member 11, and the center of the sleeve or member 11 is the center of the upper re duced portion of the stem 6, so that the position of the opening 8 in the stem 6 is not only eccentrically disposed to the axis of the re IUO duced portion of the stem 6, but is also eccentrically disposed to the aXis of the sleeve 11. The sleeve is provided with the inner tapered or beveled face 12, corresponding to the bevel ortion 7 of the upper end of the stem 6. "he upper face of the sleeve 11 is provided with the cut-out or slotted portion 13, the base of which is on a line with the up per face of the stem 6. One of the walls of such cut-out portion 13 is beveled, as at 141, and the opposite Wall shows a concave face, as at 15.

The sleeve 11 is provided in its body with a semicircular cut-out portion or slot 16 and movable in such cut-out portion or slot 16 is a stem or pinl 7, transversely carried in the upper reduced portion of the stem 6, one end of the pin 17 extending through and beyond the outer face of the stem 6, and such extension is carried in the semicircular cut-out or slotted portion 16 of the sleeve 11. Transversely disposed through the pin 17 is a wire groove or opening 18, coincident with and forming a part of the wire-o ening 8 through the stem 6. Thus it will be seen that the stem 6 may make half of a revolution before the sleeve 11 is caused to turn, which is accomplished by the pin 17 abutting with the wall of the slot or cut-out portion 16, when the sleeve will. be turned therewith, all of which will be further described.

The sleeve 11 is held under tension of a spring 19, which in this instance is a coil wound around the spindle 1, as shown in the figures, the lower end of the coil being secured at 20 to the body of the spindle and the upper end of the coil being secured at 21 to the outer face of the sleeve 11, the oflice of said spring being to draw the sleeve in the same direction of rotation in which the spin- 'dle 1 is rotated, which will be further de scribed.

In the operation of coiling the end of a staywire around a strand-wire the parts of the device will be in positions somewhat as seen in Figs. 1, 2, and 1-that is, they will be in this position at a time just previous to the starting of the coil. A strand-wire A is passed up through the spindle 1 into the stem 6 and through the opening 8 therethrough and passing througgh the wire-openings in the pins 9 and 17. isastay-wire adapted to be fed transversely to the length of the strand-wire A, and the end of such stay-wire B is carried across and through the slotted open face 13 of the sleeve 11, and said stay-wire lies be-. tween the face of the strand-wire and the groove or concave face 15 of the sleeve 11. The strand-wire A, which is carried eccentric to the sleeve 11 during a partial rotation of the spindle by reason of the eccentric disposition of the upper reduced end of the stem 6, will engage during its rotation the body of the stay-wire B and force said stay-wire B into the concave face of the sleeve 11, as seen in is directed to said stem and the sleeve thereof when the stem is revolved and the strandwire impinges u on the body of the stay, as seen in. Fig. 5, t e stay will lock the position of the sleeve until the pin 17 moves around in and the distance of the slot 16 therein, when it will abut with the opposite end of said slot 16 and cause to be rotated in the same general direction therewith the sleeve 11. Otherwise, if there were no stay or other means on the face of the sleeve to lock it against rotation as the spindle 1 was revolved the spring 19, which is fast to both sleeve and spindle, would draw the sleeve and cause it to rotate with and in the direction of rotation of said spindle; but the fact that there is meansand in this instance it is the stayto retard the movement of the sleeve the rotating of the spindle will not effect the rotation 1 of the sleeve until the pin 17 has traversed. the distance of the slot 16, when it will then cause the sleeve to rotate therewith. The strand-wire having shifted its position by reason of the eccentric disposition of the pin in the sleeve will, when it reaches a position as seen in Fig. 5, impin e upon the stay-wire and hold it rigidly in t e sleeve andinsure its tight wrappin around said strand-wire. The rotation of t e spindle and sleeve will coil the end of a stay around a strand wire, somewhat as seen in Figs. 6 and.7, and as. many more wraps made as is desirable, it being understood from the above that the transverse bearing of a stay-Wire is fixed, so that during the coiling of the end of said staywire the body of such wire leading to the coil will remain in one position, thus permitting the grooved portions 15 of the sleeve 11 in its rotation to carry with it the end .of a staywire and direct the same around a strandwire.

In coiling the ends of a stay around the strand wires it is preferable to direct the free ends of the stays always under, as seen in Fig. 7. This is accomplished somewhat as in Fig. 6 by engagement of the body of the staywire by the bevel-face 141 of the sleeve 11, which is arranged parallel with the groove 15 and opposite thereto. Thus as the sleeve 11 is rotated the bevel-face 14 thereof will ride under the body of the stay and permit the coiling portion of such stay to be direct d under, as above described and as seen in the figures.

The office of the spring 19 is to insure the sleeve 11 being always in position to receive the ends of succeeding stay-sections as they are fed tothe coiler for coiling such stay-sections around the body of strand-wires passing through the coilers. Simultaneous with the completion of a coil of the end of a stay around the strand the strand-Wire by suitable means is drawn through the coiler to permit a succeeding stay to be fed and received somewhat as seen in Fig. 4.

The drawing out of the strand-wire through the coiling-spindle relieves the tension of the stay-wire on the sleeve, when the sleeve will continue its rotation in the direction of the spindle and stem, but move faster than the spindle, caused by the spring 19, Whose office it is when the stay-wire is removed from the slotted face of the sleeve to draw said sleeve in the direction of rotation of said spindle until the opposite end of its slotted portion 16 will catch up with and abut against the pin 17, when the parts will again be in the position seen in Fig. 4 and a stay-wire dropped onto the sleeve and the same operation carried on as before for coiling the ends of all succeeding stay-sections around the strand-wires as they are drawn through the coilers.

The rotation of the stemin actual practice is very rapid, and the stopping of the sleeve is momentary and at intervals, but sufficient to adapt the dropping of a stay-section onto the upper face of the sleeve and in the open face 13 thereof.

It is preferable to rotate the spindle continuously; but it may be arranged to rotate said spindle intermittingly under certain conditions, and I do not wish to be understood as confining myself to such an arrangement; nor do I wish to be restricted to the eccentric arrangement of the strand-wire moving into position to lock the stay for tightly Wrapping the same around said strand-wire, as it is obvious that other and various changes may be made without departing from the principle and scope of invention herein.
